3 Creation and Manipulation of Solid Geometries
3.1 Predefined Solid Geometries
3.1.1 Predefined Spheres and Ellipsoids
SGofCPLcommand('sph 10');
SGofCPLcommand('sph 10 45');
SGofCPLcommand('sph 10 45 20 ');
SGofCPLcommand('sph 10 45 20 30');
3.1.2 Predefined Solid - Screws, Nuts, Thread Cutter
SGofCPLcommand('scr 5 10');
SGofCPLcommand('scr -5 10 10');
SGofCPLcommand('scr -5 10');
3.1.3 Predefined Solid – Letters and Strings
SGofCPLcommand('text Hello');
SGofCPLcommand('text Hello 100');
SGofCPLcommand('text Hello 100 50');
3.2 Manipulating Solid Geometries (SG)
3.2.1 Manipulating Solids – Chamfer Edges
SGofCPLcommand('b 10 10, c 4 3, h 4');
SGofCPLcommand('b 10 10, c 4 3, h 4, cham 1');
SGofCPLcommand('b 10 10, c 4 3, h 4, cham 1 0.5');
3.2.2 Manipulating Solids – Move in Space
SGofCPLcommand('sph 30 90 20 10,');
SGofCPLcommand('sph 30 90 20 10, move 10 20');
3.2.3 Manipulating Solids – Rotate Solids
SGofCPLcommand('b 20 10, move 5 20, b 10 40, h 4');
SGofCPLcommand('b 20 10, move 5 20, b 10 40, h 4, rotx 90');
SGofCPLcommand('b 20 10, move 5 20, b 10 40, h 4, roty 90');
SGofCPLcommand('b 20 10, move 5 20, b 10 40, h 4, rotz 90');
3.2.4 Manipulating Solids – Melting Separated Solids
SGofCPLcommand('c 4, h 2, c 2, h 10 -1'); VLFLplotlight (1,0.5);
SGofCPLcommand('c 4, h 2, c 2, h 10,-1, melt'); VLFLplotlight (1,0.5);
3.2.5 Manipulating Solids – Text Stamp on Surface
SGofCPLcommand('c 4, h 2, c 2, h 10,melt, textstamp'); view(-105,50); camlightTL;
SGofCPLcommand('c 4, h 2, c 2, h 10,melt, textstamp Yilun-Sun'); view(-105,50); camlightTL;
3.2.6 Manipulating Solids – Copy Radial
SGofCPLcommand('sph 1, move 2, dupr 7');
SGofCPLcommand('c 1, h 1, move 2, dupr 7');
3.2.7 Manipulating Solids – Copy with Spatial Distance
SGofCPLcommand('sph 10 45 20 30, dups 2 2 2 ');
SGofCPLcommand('sph 10 45 20 30, dups 2 2 2 5 ');
3.2.8 Manipulating Solids – Copy on Grid
SGofCPLcommand('sph 10 45 20 30, dupg 2 2 2 10');
SGofCPLcommand('sph 10 45 20 30, dupg 2 2 2 20');
3.2.9 Manipulating Solids – Hollow Solids
SGofCPLcommand('b 10, h 10, hollow 1'); VLFLplotlight(1,0.2);
3.2.10 Manipulating Solids – Cutting Solids
SGofCPLcommand('b 10, h 10, hollow 1');
SGofCPLcommand('b 10, h 10, hollow 1, cutz 8');
SGofCPLcommand('b 10, h 10, hollow 1, cutz 3 8');
3.2.11 Manipulating Solids – Create a Shell for a Solid
SGofCPLcommand('b 10, h 10, shell 1 1');
SGofCPLcommand('b 10, h 10, dup, shell 1 1, add, cutz 5'); VLFLplotlight(1,0.2);
